Page 3: Warnings
Warnings • This SART is an emergency device for use only in situations of grave and imminent danger. • False alarms cost lives and money. Help to prevent them; understand how to activate and disable your equipment. • Read the complete manual before installing, testing or using the SART. -
Page 4: General Description
General description The SART (Search And Rescue Transponder) is designed for survivor location during search and rescue operations. CARRY-OFF SART Supplied as one integral unit. This is normally mounted in a bulkhead bracket (supplied) which is used to stow the unit on the mother vessel. On abandoning to a survival craft the SART can be carried in one hand off the stricken vessel and mounted through a port in the canopy of the survival craft using the telescopic pole. - Page 5 The SART operates by receiving a pulse from the search radar and sending back a series of pulses in response, which the radar will then display as if they were normal echoes. The first return pulse, if it sent back immediately, will appear in the same place on the PPI as a normal echo would have done.

Page 6: Installation
Installation The preferred mounting location is inside the vessel, and protected from the elements, usually on the ship’s bridge wing. The SAR should be mounted where it will not get in the way of day-to-day operations, but where it can readily be accessed near an emergency exit in the event it is needed. -

Page 9: Self Test Facility
It is recommended that battery change should only be performed by an authorised McMurdo service agent, in order that a complete assessment and integrity check can be performed. The replacement battery kit is McMurdo part number 86-630. -
Page 10: Technical Description
Technical description A single switched antenna is used for both receive and transmit functions; the switch normally connects the antenna to the receiver circuit. In the standby state only the receiver portion of the SART is powered to reduce battery consumption to a minimum. -

Page 12: Operation Of Marine Radar For Sart Detection
Operation of marine radar for SART detection Radar Range Scale When looking for a SART it is preferable to use a range scale between 6 and 12 nautical miles. This is because the spacing between the SART responses is about 0.6 nautical miles (1125 metres) and it is necessary to see a number of responses to distinguish the SART from other responses. -
Page 13: Anti-Clutter Sea Control
Anti-Clutter Sea Control For optimum range SART detection this control should be set to the minimum. Care should be exercised as targets in sea clutter may be obscured. Some radar sets have automatic/manual anti-clutter sea control facilities in which case the operator should switch to manual. -
